Last week's Masters champion Jon Rahm shook off his poor opening round and rebounded with Friday's best score, while Jimmy Walker opened up a three-stroke lead at the RBC Heritage.

Rahm had a bit of a hangover following his second major victory, beginning his week at Harbour Town Golf Links with a one-over 72, before showing the field how it was done with a seven-under 64 on his second trip around the course.

He birdied holes two, three, four and five to kick-start a bogey-free round with seven birdies overall, jumping from the wrong side of the cut line to a tie for 18th at six under.

Meanwhile, at the top of the leaderboard it was Jimmy Walker who raced clear of the pack, posting his second 65 in a row to head into the weekend at 12 under.

Walker, 44, is a six-time winner on the PGA Tour, but his last victory came at the 2016 PGA Championship, and he came into this event with only four made cuts from 12 starts this season.

He has his work cut out for him to hold off a star-studded chasing pack, with world number two Scottie Scheffler joined by major champion Justin Rose and world number six Xander Schauffele at nine under.

Fellow top-10 talents Patrick Cantlay and Viktor Hovland are one stroke further back at eight under, where they are joined by English duo Aaron Rai and Tommy Fleetwood in a tie for fifth.

Jordan Spieth is tied for 10th at seven under with a group that includes Rickie Fowler and former RBC Heritage champion Matt Kuchar, and Rahm is joined at six under by reigning U.S. Open champion Matt Fitzpatrick.

Young South Korean phenom Tim Kim missed the cut by one stroke, while Max Homa had a week to forget, finishing at three over to miss the cut by five strokes.

Play was suspended in Thursday's opening round of the RBC Heritage with Viktor Hovland clinging onto the outright lead following his seven-under 64.

It was a great first trip around Harbour Town Golf Links for the Norwegian, going bogey-free with seven birdies.

Hovland, 25, is coming off some terrific results, tying for third at The Players Championship in March before a tied-seventh finish at the Masters last week.

He leads by one stroke from Jimmy Walker, Aaron Rai and Brian Harman, although Harman is the only of the trio to have finished their round, with Walker still having two holes to play, while Rai has three more to try and track down Hovland.

There is a logjam tied for fifth at five under including major champions Matt Fitzpatrick, Zach Johnson and Justin Rose, with Rickie Fowler and Xander Schauffele a further shot back at four under.

Defending champion Jordan Spieth is joined by world number two Scottie Scheffler and three-time champion at this event Stewart Cink at three under, while top-10 talents Justin Thomas and Patrick Cantlay headline the group at two under. 

Last week's Masters champion Jon Rahm shot a disappointing one-over 72, and world number seven Max Homa (two over) is also on the wrong side of the cut-line heading into Friday.

Jon Rahm birdied the last hole of his first round to join Viktor Hovland in a share of the Masters lead.

Hovland held a three-shot advantage at one stage as he started the first major of the year with a magnificent seven-under 65 on Thursday.

Rahm matched the Norwegian's round to become the co-leader at Augusta National after starting with a double bogey.

The 2021 U.S. Open champion eagled the par-five eighth to go three under and fire a warning to the rest of the field.

Rahm birdied the 13th, 15th and 16th before rolling in a short putt for another gain at 18 following a brilliant approach shot.

Hovland had earlier signed for his lowest Masters round and his joint-best in a major, ending his day without a solitary bogey in great conditions.

Cameron Young and Brooks Koepka are just two shots behind the leading duo, with fellow American Sam Burns also five under through only eight holes.

Jordan Spieth, Shane Lowry, Xander Schauffele, Adam Scott, Joaquin Niemann and Sam Bennett are well poised on four under.

Bennett matched the record for the best front nine by an amateur in the Masters, hitting the turn in 32.

Defending champion Scottie Scheffler was two under approaching the turn, while Rory McIlroy and Tiger Woods are one over and two over respectively in Georgia.

Will Zalatoris withdrew from the prestigious event due to injury.

Jon Rahm was the major casualty from the WGC Match Play on Friday as Scottie Scheffler, Rory McIlroy and Patrick Cantlay all advanced with perfect records.

The Spanish second seed was dumped out after losing 5 and 4 to 2021 WGC Match Play winner Billy Horschel in their final Group 2 match at the Austin Country Club in Texas.

Horschel went 1-up with a par on the second hole and never relinquished the lead, with Rahm failing to register a birdie throughout the day's play.

The 36-year-old American pulled away with birdies on the 10th and 11th holes followed by a 21-foot birdie putt on the 14th to clinch a spot in the round of 16 against Cameron Young.

Horschel progressed in a tight group with a 2-0-1 record ahead of Rickie Fowler (2-1-0), Rahm (1-2-0) and Keith Mitchell (0-2-1).

Top seed and reigning champion Scheffler advanced after beating Tom Kim 3 and 2 to round out a 3-0-0 group stage record.

Kim came out strong with birdies on the first two holes to go 2-up, but Scheffler rallied back immediately winning three of the next four holes.

Third seed McIlroy topped Group 3 unblemished after beating Keegan Bradley 3 and 2, while fourth seed Cantlay beat Brian Harman 2 and 1 to top Group 4 with a 3-0-0 record.

Kurt Kitayama won a three-way sudden death playoff over Tony Finau and Adrian Meronk to progress atop Group 10.

Canadian Mackenzie Hughes produced an upset to advance via Group 12 from Taylor Montgomery who he beat 6 and 4. Jordan Spieth, who beat Hughes on Thursday, missed out after losing to Shane Lowry 2 and 1.

J.J. Spaun also pulled off a surprise by topping Group 11 with a 3-0-0 record, downing Min Woo Lee 2 and 1 to seal his progress.

Max Homa, Xander Schauffele, Andrew Putnam, Matt Kuchar, Sam Burns, Lucas Herbert, J.T. Poston, Jason Day and Young also all progressed into Saturday's last 16 knockout stage.

Jon Rahm's brilliant recent run came to a dramatic halt in windy conditions as he slipped down the leaderboard on day two at the Arnold Palmer Invitational on Friday, with Kurt Kitayama taking a two-stroke lead.

Rahm, who has claimed five wins from his past nine starts worldwide, had led the event after an opening-day seven-under 65 but carded a four-over round of 76 on day two to be six strokes off the pace at three-under overall.

The Spaniard's round saw him come back to earth, falling away dramatically late with three bogeys and a double bogey in his final five holes at the Bay Hill Club and Lodge in Florida.

Rahm's struggles opened the door for Kitayama, who had been joint second after the first day. Kitayama backed that up with a four-under 68 with five birdies and one bogey to be nine-under overall.

Kitayama has led three events this season after 36 holes and is yet to convert any into victories.

Over Kitayama's shoulder is three-time major winner Jordan Spieth who found his putting groove to card a three-under-par 69, sitting two shots off the lead at seven-under overall. Spieth might have been closer if not for a bogey on the 18th after a poor drive.

Xander Schauffele and Corey Conners are tied at six under, with Davis Riley, Patrick Cantlay, Matt Fitzpatrick and Justin Thomas behind them at five under. Conners carded the day's best round with a six-under 66.

Last month's Honda Classic winner Chris Kirk was tied for second after the opening day but also dropped away with a day-two 75 that included two double bogeys.

Among those to miss the projected cut, with play suspended with two players left on the course, were Collin Morikawa, Tom Hoge and Hideki Matsuyama.

Jon Rahm lived up to his billing as the hottest talent in professional golf after starting his week at the Arnold Palmer Invitational with a seven-under 65 on Thursday.

Rahm, the world number one, boasts five wins from his past nine starts worldwide and has not finished an event outside the top 10 since finding himself in a tie for 15th in August's Tour Championship.

Coming off a victory in his most recent outing at the Genesis Invitational, Rahm is looking to secure another of the PGA Tour's new elevated events, with the increased prize pool drawing 44 of the world's top-50 players to the famous Bay Hill course.

He certainly made a promising start in Florida, heading into day two with a two-shot lead at the top of the leader board.

Rahm began his day with three consecutive birdies and finished with another two on 17 and 18 having carded an eagle on the par-five 16th.

His sole bogey came on hole eight, failing to recover a par after a wayward tee shot.

Another competitor coming off a win in his most recent start, last week's Honda Classic champion Chris Kirk is tied for second at five under with Cameron Young and Kurt Kitayama.

Not a single player finished their round bogey-free, but Kitayama and Max Homa (two under) made it through 17 holes before their first blemishes came on the 18th.

The group tied for fifth at four under includes some of the game's biggest stars, with world number two Scottie Scheffler joined by three-time major winner Jordan Spieth, Patrick Cantlay, Xander Schauffele and resurgent fan favourite Rickie Fowler.

Max Homa and Keith Mitchell are tied for the lead after Thursday at the Genesis Invitational, but all eyes were on Tiger Woods as he finished his opening round with three consecutive birdies.

In his first non-major PGA Tour start since October 2020, Woods displayed impressive physical capabilities, often out-driving his playing partners Rory McIlroy and Justin Thomas.

The 15-time major champion birdied his first hole – to a raucous ovation – but he had three bogeys and one birdie over his next 11, reaching the 15th at one over.

He proceeded to electrify the audience with a birdie after a beautiful approach on the par-three 16th, before following it with a long-range birdie putt on the par-five 17th, and another picture-perfect approach on the last set him up for his third birdie in a row to finish at two under.

Playing partners McIlroy (four under) and Thomas (three under) both also birdied the 18th in a thrilling finale for the featured group.

Homa and Mitchell were the only players to shoot seven-under 64s during their first trip around Riviera Country Club, while the red-hot Jon Rahm is alone in third at six under.

Collin Morikawa is part of the three-man group at five under, McIlroy headlines the group at four under, and Thomas is joined by Patrick Cantlay and Rickie Fowler at three under.

There is a loaded group with Woods at two under, including Viktor Hovland, Will Zalatoris, Xander Schauffele and Im Sung-jae.

Scottie Scheffler won his first PGA Tour title 12 months ago at the Waste Management Phoenix Open, and he is looking to defend that crown as he heads into the weekend with a two stroke lead at 10 under.

A large chunk of the field still have between five and eight holes remaining before they complete their second round, with a delay on Thursday creating a backlog as players had to finish their first round early Friday morning.

Scheffler was part of the early group and followed his opening 68 with a seven-under 64, and he was the only player to shoot seven under on his second trip around TPC Scottsdale.

It is shaping up as a tantalising battle at the top of the leaderboard after Jon Rahm's 66 clawed his way into a tie for second at eight under, where he is joined by round-one leader Adam Hadwin, who still has eight holes to play.

Im Sung-jae will have his sights set on posting the best second-round score, with time being called while he was six under through 12 holes, and tied for fourth with Wyndham Clark at seven under overall.

The only other player with a second-round score of six under or better was Venezuela's Jhonattan Vegas, rebounding strongly from an even-par opener, and he has four holes remaining to try and match Scheffler's heroics. 

Also in a tie for sixth with Vegas are former world number one Jason Day and current world number six Xander Schauffele, while the dangerous duo of Tom Kim and Jordan Spieth are one further back at five under.

Major champions Justin Thomas and Rory McIlroy are still in the hunt at three under, Viktor Hovland is at two under, and Hideki Matsuyama is at one under with five holes to play.

Half the field still need to complete their opening round, but Nick Taylor and Adam Hadwin raced around with the early group to take a share of the lead into Friday at the Waste Management Phoenix Open.

Taylor had a rollercoaster of a round, posting a one-over front-nine after an eagle, a double-bogey and a bogey, before flying home with six birdies on the back-nine to finish at five under.

He is joined by Canadian compatriot Hadwin as the only players to finish rounds of 66, but there is a strong chasing pack who were unable to finish that will look to snatch the round-one lead on Friday morning.

World number six Xander Schauffele is one stroke off the lead at four under, although he has finished his round, while joining him in a tie for third are former world number one Jason Day (through 10) and American Jim Herman (through 13).

The red-hot Jon Rahm will have his sights on the top, sitting at three under with five holes to play, as will both Max Homa and Keegan Bradley who are also at three under with six holes to play.

Major champion Matt Fitzpatrick is joined by Tony Finau, Sam Burns and Im Sung-jae in the group who completed one-under rounds, while Jordan Spieth posted an even-par 71.

Justin Thomas (one over through 12) will have a chance to still finish his first round under par, while Collin Morikawa, Patrick Cantlay and Cameron Young will all be trying to fight their way back into contention after finishing two over.

Jon Rahm has now won back-to-back PGA Tour starts after repelling the challenge of Davis Thompson at The American Express.

Rahm, who came from behind at the Sentry Tournament of Champions earlier this month, also closed 2022 with DP World Tour victories at the Spanish Open and the DP World Tour Championship, giving him four wins from his past six starts overall.

He came into the final round at PGA West's Pete Dye Stadium Course tied for the lead at 23 under, and after rounds of 64, 64 and 65, he closed with a four-under 68 to post a winning score of 27 under.

Rahm reached the 16th hole tied with Thompson for the lead, but he produced a clutch birdie on the par five while Thompson could only scramble for par following a wayward tee shot.

Thompson almost tied things up at the picturesque par-three 17th, but his 50-foot putt crashed into the flag stick and somehow stayed out.

There would be no late twists in the tale, as Rahm found the bunker with his tee shot on the last but followed it with a perfect approach, while Thompson did not leave himself a birdie putt.

The 23-year-old Thompson finished alone in second at 26 under for his best ever finish on the PGA Tour, while some terrific Sunday scores were posted to climb into the top 10.

World number six Xander Schauffele tied for the round of the day as he shot a 10-under 62 to climb into a share of third at 25 under. He was matched by South Africa's Erik van Rooyen, who also posted a 62 to finish tied for sixth at 23 under with rising South Korean star Tom Kim.

After two rounds at The American Express it is Davis Thompson and Jon Rahm who have broken away from the field, both at least three strokes clear of third place.

Thompson was the first-round leader after riding back-to-back eagles to a 10-under 62 – the best score of his PGA Tour career – and he added three more eagles in his second round to follow it up with a 64 and head into the weekend at 18 under. His five eagles ties the PGA Tour record for the most through 36 holes at any event.

He is two strokes clear of Rahm at 16 under after the world number four went bogey-free for his second 64 in a row.

Both players began their week on the La Quinta Country Club course, and both played the PGA West's Nicklaus Tournament course on Friday. They will play Saturday's round on the PGA West Stadium Course, which is also where Sunday's final round will be contested.

There are some big names in the chasing pack, with South Korean rising star Tom Kim and former world number one Jason Day part of a five-man group at 13 under.

Patton Kizzire is alone in eighth at 12 under, while world number six Xander Schauffele rounds out the top-10 in a tie for ninth at 11 under.

World number two Scottie Scheffler and number five Patrick Cantlay are still in the hunt at 10 under, while number seven Will Zalatoris is one shot inside the theoretical cut line at six under, but all players will get one more round before the cut at the conclusion of round three.

Davis Thompson produced back-to-back eagles on his way to a two-stroke lead after opening with a 10-under 62 at the American Express in California on Thursday.

The unheralded 23-year-old American leads the way from a stacked field that includes 10 of the top 20 in the world.

Thompson set up his career-low round by shooting an eight-under-par 28 on his front nine, including eagles on both the fifth and sixth holes at the La Quinta Country Club, which is one of three courses being used as players also spread across the PGA West's Stadium Course and Nicklaus Tournament Course.

The American's performance tied the lowest front-nine score on the course, having made six of seven fairways and eight of nine greens.

Behind Thompson is a group of five players, including former world number one Jon Rahm who carded nine birdies and a bogey in his round of 64 on La Quinta. Rahm is tied with Sam Burns, Tyler Duncan, Matti Schmid and Taylor Montgomery at eight under.

Burns might have been outright second if not for a bogey on the 18th on the Stadium Course, having carded seven birdies on his front nine. The American made nine consecutive one-putts.

Nine players are a further stroke back at seven under after the first round, including Tokyo Olympics gold medalist and two-time major runner-up Xander Schauffele, who also shot an eagle on the fifth.

Among the pre-tournament favourites, Scottie Scheffler and Patrick Cantlay both shot four under on La Quinta, while Will Zalatoris managed three under on the Nicklaus Tournament Course. Tony Finau and Tom Kim carded rounds of three under at La Quinta.

Viktor Hovland survived a nervy finish on his way to back-to-back Hero World Challenge titles as he finished at 16 under for a two-stroke victory.

Hovland defeated Scottie Scheffler by one stroke in last year's edition, and by defending his crown, he joined Tiger Woods (2006 and 2007) as the only other player to win this event in consecutive seasons.

He entered Sunday's play at the Bahamas' Albany Golf Course with a three-stroke buffer, but was made to sweat in the middle stages as playing partner Scheffler eagled the par-five sixth hole to cut the margin to just one.

Scheffler could not keep it up, posting a bogey and a double-bogey to close the front-nine and give Hovland some breathing room. However, he came roaring back down the stretch, with three consecutive birdies on 14, 15 and 16 to pull to within two.

The Norwegian opened the door on the 18th and final hole, with his tee shot finding the rough, before his next shot went in the water, but he was able to pitch and one-putt to save a bogey, meaning Scheffler had to birdie the hole to force a play-off.

Scheffler could not hit the green in regulation to give himself a birdie putt, and lipped out with his chip, finishing with a par to claim the runner-up spot yet again as the world number two shot a 68 while Hovland finished with a 69.

Speaking to NBC after stepping off the final green, Hovland did not hide his relief after surviving his late blunder.

"It's freaking nerve-wracking," he said. "I mean I was leading by five I think after the turn, but still, you're never that comfortable.

"I didn't play all that great on the back-nine, but it was good enough.

"We're at an amazing resort, there's only 20 guys – but it's the best 20 guys in the world, basically."

Cameron Young finished outright third at 12 under, with Xander Schauffele in fifth at 11 under and Justin Thomas rounded out the top five at 10 under.

Reigning champion Viktor Hovland carded a round-of-the-day eight-under-par 64 to pull three shots clear at the Hero World Challenge on Albany Golf Course in the Bahamas on Saturday.

The Norwegian, who was the joint leader after day one and outright leader by one shot at halfway, shot 10 birdies in his stunning third round to open up a three-shot gap on Scottie Scheffler.

Hovland could have been further ahead if not for a bogey on the par-four 18th hole, having managed six birdies in the previous seven holes to card 31 on his back nine. He also bogeyed on the sixth hole.

The reigning champion, who managed eagles in both of his first two days, fired in a dart over the water off the tee on the par-three 17th hole to set up a routine birdie putt.

Hovland leads from world number two Scheffler, who hit 66 on day three, to move up to 10-under overall.

Scheffler buried an eagle putt on the par-five 15th hole to move into solo second, having five birdies for his round, along with a bogey.

Justin Thomas is a further two shots behind Scheffler at eight-under overall, alongside Cameron Young who had been in the four-player pack one stroke behind Hovland at halfway.

Collin Morikawa and Xander Schauffele are tied at seven under, rounding out those in contention with a big gap to the next best, Jon Rahm who is four-under overall.

Viktor Hovland is alone atop the Hero World Challenge leaderboard after Friday's second round, following his opening 69 with a two-under 70 to enter the weekend at five under.

Hovland, who was the joint-leader entering the day, is the reigning champion at the event after edging Scottie Scheffler by one stroke at Albany Golf Course in the Bahamas last year.

In an action-packed second round, the Norwegian posted an eagle with four birdies and four bogeys, with his slam-dunk shot of the day on the par-five sixth hole making it back-to-back rounds with an eagle.

He is one stroke clear of a four-man group consisting of Scheffler, Xander Schauffele, Cameron Young and Collin Morikawa, with playing partners Scheffler and Schauffele posting four-under 68s to tie for the round of the day.

South Korean 20-year-old Tom Kim is the only player in sixth at three under, Justin Thomas is alone at two-under, and Billy Horschel is tied with Tiger Woods' late replacement Sepp Straka for eighth at one under.

It leaves 11 of the 20-player field at least five strokes off Hovland's lead, with Matt Fitzpatrick, Tony Finau and Jon Rahm at even par.

It was a day to forget for Tommy Fleetwood, Corey Conners, Max Homa and Shane Lowry, with all four shooting their way out of contention with rounds of four over or worse.
